CORK STOPPER
Joseph W..Fay, Villa. Park, 111., assignor of one
, half to Ersyl F. Chambless, Chicago, Ill.
Application July 5, 1934, Serial No. 733,743
' 6 Claims.
The present invention relates generally to
closures for bottles and like receptacles, and is
particularly concerned with the provision of a new
and improved form of ?anged or headed stopper.5
As ordinarily formed, stoppers of the type with
which my present invention is concerned are
formed of cork or other compressible material.
Where the ?anged or headed portion is formed
as an integral part of a cork stopper it has been
10 necessary to start with a relatively large cork
having a diameter at least as large as the head
desired and to grind the cork down to the desired
(01. 215-48)
of the stopper, and at the s‘ame‘time be effectively
and securely restrained against pulling out and
against turning along the curvature of the slit in
the manipulation of the’stopper after the cork is
applied.

The anchoring prong or prongs'may, within
the scope of the present invention, be formed in
tegral with the ?ange or head forming cap or
may be made separately and applied, as will here
inafter more fully appear.

Further features and advantages and a con

To avoid these disadvantages, it has‘ been proposed to attach to a cork of the desired size a
?anged or head portion, usually of '- wood, and

the body of the cork, butthis has not been suit-

My invention aims to provide a ?anged or
headed stopper which is less expensive than the
corks or stoppers with integral ?anged or headed
portions of the same material as the body of the

?anged or vheaded portion is attached in a better
and more secure manner than heretofore.

a stopper, preferably one formed of a compressible
material such as cork. In the form of the inven
tion shown in Figure l, the stock from which the
?anged cap I is made is provided with extended
sections, preferably integral with the portion of
the stock from which the ?ange 2 is formed.
These extensions, when formed, are provided with
a pair of prongs ‘I and 8 connected integrally
with the ?ange 2 by angularly disposed sections l0
10 and | | formed to lie against the central section 3
and the ?ange 2, as shown in Figure 1', the prongs
being resilient.
The anchoring prongs ‘I and 8 are of especial
importance in the present invention. Each of
15 these prongs is formed with a central arcuate and
axially extending portion |5 having laterally di
rected teeth H on each side, slightly curved
reversely to the curvature of portion l5.
These
teeth are preferably cut so that they are of gen
20 erally ?sh-hook formation.
That is to say,’ the
ends thereof are directed laterally and also in a
direction towad the cap piece I. By virtue of this
formation, whenever the cap‘ piece I with the
prongs '| and 8 is applied to a cork and the
25 prongs forced into the material of the body por
tion of the cork or_stopper, the teeth |'| facilitate
entry of the prongs and, at the same time, effec
tively bite into the body of the cork or» stopper
so as not only to prevent the withdrawal of the
30: cap piece from the stopper but also to prevent the
rotation of the cap piece relative to the stopper,
the prongs twisting slightly so as to increase the
conical, it is to be understood that it could be
cylindrical or any other desired or necessary
shape.
The cap piece is indicated in Figures 4,
7 and 8 by the reference numeral 4| and includes
a central section 42 and a ?anged portion 43.
In this case the cap piece 4| has its central sec
tion 42 formed with a pair of slits 44 and 45,
each central portion of which is curved and each
having end portions disposed at an angle thereto.
A U-shaped anchoring stud is employed with 10
the cap piece 4| and is indicated in its entirety
by_the reference numeral 50. The anchoring
stud means 50, shown in Figures 4 to 8, is a part
separate from the cap piece proper, whereas in
Figures 1 to 3, the anchoring stud means is formed 15
integrally therewith. In Figure 4 the central
portion 5| of the anchoring stud means 50 is
shown as embracing the portion 53 of the cap
piece 4| between the slits 44 and 45 in such a
manner that the prong sections 55 and 56 extend 20
in an axial direction relative to the cap piece 4|
and the stopper 40. The prong sections 55 and
56 are preferably of the same construction as the
prongs ‘I and 8 shown in Figure 1; that is, each
prong is provided with a central axially extend 25
ing curved section 51 and reversely curved later
ally fiaring tooth portions 6|] of ?sh-hook forma
tion. It will be observed that the end portions
of the slits 44 and 45 are of approximately the
same angularity as the teeth 60 on the anchoring
prongs 55 and 56. This facilitates the insertion
of the anchoring member 50 in the slits 44 and 45.
Figure 6 illustrates the stock, partly processed,
grip of the teeth.
While I have shown two prongs ‘l and 8, it will
r be apparent that the present invention could be

and it will be noted that the flat stock is formed

de?ning a circular head or disc at the upper ends
of the prongs. During the shaping of the blank,
the prongs 15 are curved transversely so as to be
of arcuate cross-section, and the teeth ‘I’! are
curved reversely to the prongs, in the same man
ner as in Figure 1. A cap 18 is then secured to
the disc at the upper ends of the prongs in a
suitable manner, as by means of a bead 19 formed
at the lower edge of the cap and tightly clamped
10 over the edge portion of the disc, as in Figure 13.
If desired, this bead may be welded or otherwise
suitably secured to the disc to prevent relative
movement between the parts.
With the exception of the form shown in Fig
forms in which my invention has been embodied,
it will be apparent to those skilled in the art that
my invention is not to be limited to the speci?c
details shown and described, but that, in fact,
widely different means may be employed in the
practice of the broader aspects of my invention.
What I claim, therefore, and desire to secure
by Letters Patent is: g
1. A stopper comprising a body of compressi
ble material and a cap having a thin anchor pro
10
jecting therefrom, said anchor having a curved
central portion and serrated edges disposed out
of the direction of curvature of said curved cen
suitable tool 80, shown in Figure 11, is used. This
tral portion and adapted for anchoring the cap
to the body of the stopper, said anchor being 15
resilient.
2. A stopper for bottles and the like compris
ing a body of compressible material having an
arcuately shaped slit formed in the central por
tion thereof, a stopper cap disposed on said 20
body, and an anchoring prong carried by said
cap adjacent the central portion thereof and hav
ing a central curved section corresponding to the
curvature of said arcuate slit, and outwardly
25 tool includes a head 8! carrying a tubular section
?aring toothed edges disposed outside of said 25
82, the end opposite the head 8| having a cutting
curved section so that when the stud is forced
into said arcuate slit the toothed edges bite into
and secure the cap on said stopper body.
3. A bottle stopper comprising a body por
tion, a cap piece mounted thereon, and an 30
15 ures 2 and 3, all of the anchoring means de
scribed above is in the form of, or includes por
tions which serve as, arcuate or curved sections.
According to the preferred form of the invention,
the stopper body, usually cork, which receives
20 the stopper caps of Figures 1 to 12, is preferably
formed with an arcuate or circular slit for the
purpose of facilitating the insertion of the an
choring prongs or stud means. To this end, a
edge 83. The cutting tool is rotated as it is forced
downwardly into the stopper 1&0 to the position
shown in Figure 11, and cuts a circular slit in the
30 central portion of the stopper, the curvature of
this slit preferably corresponding to the curva
ture of the prong sections. Cutting the cork in
arcuate anchoring stud carried by said cap piece
and having serrated edges disposed out of the
this manner facilitates the attachment of the
direction of the arcuate part of the stud so that
cap piece and the anchoring means which it
carries. The cutaway sections or portions of the
anchoring means cooperate with the material of
the stopper 4!] effectively to lock the cap piece
thereto, both against axial displacement and rel
ative rotation. When the stopper is forced into
when the stud is forced into said body portion the
cap piece is secured against separation from and 35
against turning with respect to said body por
tion.
4. A cap for bottle stoppers and the like hav
ing a thin anchor projecting therefrom, said an
40 the neck of a bottle, or like container, it is com
pressed, such compression of the stopper render
ing the attaching means even more effective by
forcing the material of the stopper into tight
contact with the anchoring means and between
45 the teeth or into the openings thereof. This is
particularly true when the stopper is formed of
cork or like highly compressible material. A
closure made in this manner can be applied and
removed a great number of times without destroy
ing or reducing its efficiency.
50
When anchoring means having prongs or non
arcuate or ?at cross-section are employed, the
stopper is cut by suitable means to provide there
in non-circular slots corresponding to the shape
of the prongs. It will be understood that the
55
prongs of anchoring means may be variously
shaped and disposed, and that the stopper may
be cut or slotted accordingly.
While I have shown the anchoring means as
60 being initially formed integrally with the cap, in
certain forms of my invention, it will be under
stood that, if desired, the anchoring means may
be ?rst formed separately from the cap and then
secured thereto by welding or equivalent means.
This is an obvious variation, and need not be il
05 lustrated nor described in detail.
While I have described above the preferred
chor having a curved central portion and a ser
rated edge disposed out of the direction of curva
ture of said curved central portion.
5. A bottle stopper comprising a cap mem
ber, a body member of compressible material hav
ing a generally centrally disposed circular slit
40
therein, and an anchor member of a curvature
adapted to ?t said circular slit, said anchor mem
ber comprising a prong pressed into said slit to
secure said cap and body member together and
provided with serrated edges for securing said
prong in said slit, said serrated edges being dis
posed out of the direction of curvature of said
slit.
6. A bottle stopper comprising a cap member,
a body member of compressible cork-like mate
rial having a curved slit within the periphery
thereof, and a curved anchor member secured
to the central part of said cap member and
having an anchoring section disposed in said slit
and provided with anchoring serrations along its 60
opposite edges, said anchoring serrations be
ing disposed out of the path of curvature of the
slit and said anchor member being of less than
complete annular form and securing said cap
member and body member together.
